  • Inverter control strategy for a transient heavy load
    Patent number: 11258297
    Abstract: A power converter system including a DC bus, a DC/DC converter coupled to the DC bus, an inverter coupled to the DC bus and configured to convert DC power from the DC bus into output AC power having an output current, an output coupled to the inverter and configured to provide the output AC power to a load, and at least one controller configured to identify an impending high-load transient state at the output, and in response to identifying the impending high-load transient state, reduce a peak value of the output current of the output AC power by operating the DC/DC converter to reduce a voltage level on the DC bus and increasing a duty cycle of the inverter.
